Research findings
Comparative structure study
The largest recorded chain role, Advanced materials / Basic and process materials, contains 104 records (80.6% of this 129-record cohort). Companies may carry multiple labels in this dimension; participation rates are not additive market shares.
The recorded sub-industry label Polymers and composite materials accounts for 9.3% here (12/129), compared with 7.4% in the parent set (37/502), an absolute gap of 1.9 percentage points.
6/129 companies link to pages with existing source-supported excerpts (4.7% of the cohort). The other 123 records remain usable for archive composition, but do not support new operating case studies.

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.
Intersection with 2026 local lists
0 of this cohort’s 129 records link through existing company-ID mappings to 2026 lists from all jurisdictions (0.0%). This intersection measures list linkage, not successful recognition or company growth.

Jiangsu Company Archive StudyRecorded roles and delivery checks
Material delivery requires stable-production evidence
The Functional materials and advanced-material platforms label covers 57 records (44.2% of this cohort). This archive clue raises a verification question about Materials of defined composition and form with batch documents; it does not establish that these companies already deliver it.
